This present invention relates to newjand useful improvements in a seed drillshoe regu-v later and has for its primary object theprovision of a simple and inexpensive structure which may be readily incorporated in the seed drill of conventional type without materially alteringlthe construction. or substantiallyincrasing the cost thereof.

-Another object of the invention resides 10 the provision of a seed. drill shoe regulator Whichimay bereadily applied'and the necessary manual adjustments made as required to regulate the depth of'operation of the shoe,-

without the employment of special tools or an A further object of the'invention resides in the provisionof a seed drill shoe regulator of the character stated which may be readily adjusted on the shoe for riding on the ground zqsurface andthusregulatingthe depth of travel of the shoe, in the ground, simply by changing the position of the adjustable sliding Wedge constituting the regulatingmember of the newstructure and operable between t the edge ofthe shoeand the surface engag ng 7 member.

- A still further object ofthe invention re sides-in the provision of aseed drill shoe regulator of the character stated which is of To the accomplishment of these and related objects as will become apparent as the description proceeds,'my' invention resldes 1n the construction, combination and arrange 'mentof parts as shall be hereinafter more fully described, illustrated in the accompanyg 1 hereunto appended.

The invention will be best understood and can be more clearly described'when reference is had to the drawings forming a part of this disclosure wherein like, characters indicate like parts throughoutthe several views.

Referring more in; detail to the drawings, it is to benotedthat thedepth at which the Figure 5' is a s milar view "of a. special 1 flanged washerconsti'tutinga, part of the ten-l SlOIl regulating means for the'ground surface shoe 12 ofthe seedfldrill lloperatesbel'ow, the ground surface, is regulated by the'posi-H tion of the groundsurface engagingmember 13 vertically of the shoe 12and with respect to the flower working edge of the latter, as

will be dearly er o djas the description 5 proceeds.

I The surface engaging member-l8 is'in the,

form of a longitudinally curved strip of metal or other suitable material and has I its upper end secured to the inclined curved suspending bar 14 connecting with the upper forward corner of theshoe 12. h The pivot pin 15employed for this purpose is, GXlZGIldGditIflHS-y versely through the bar Hand through pair of parallel ears bentupfrom the side edges of the strip 13, near thelend thereof and en- 'gaged against the sides ofthe barlt and over the top thereof. The tension of the strip 13 is regulated by an expansion spring 17 on strip 13, a short distance from the upper end.

thereof and then through the barl li The lower end of -the spring 17 bears against the special washer 19 011 the bolt-18 and having the bolt 18 directed,upwardlyfthroughthe downturned side flanges 19 'engaging the sides of the bar 14, An appropriate stop nut 20 is secured on the upper extremity of the bolt l8 and serves as an adjustable bearing for the upper end of the springl'l' for regulating the tension thereof and the consequent tene 7 sion on the strip 13L The strip'13 is split ole bifurcated inwardly i from it ilower free end along its longitudinal" centre for about one-half thelength thereof,

1 thus providing the spaced legs 21 which work with spaced teeth on their rearwardly in-- clined upper ed e 1' The flanges 22 are shown as being extended from the outer longitudinal on the opposite sides of the shoe 12 and ride on the-ground surface at all times, during operation of the seed drill.- Upstanding, in? clined flanges 22 are provided on the legs 21,

edges of the legs 21andibent'ba'ck over the upper faces thereof to the inner longitudinal edges of the legs 21 and thendirected upf wardly in parallel spaced relation. I

The adj ustable regulating member is in the form-of a sliding wedge 24 which iselongated and works between tlie;curved,'inclined lower vtheidesired"tension'dn theistrip 13 and thereface of the jshoe 12 and the upper face of the 13. The-- sliding Wedge 2 1 is'bifurcated from its lo were-rear end for the g-reater portion o'f'i'ts' length,thus providing the arms which extend on the opposite sides of the shoe 2 1 2, above't-heflegs 21 of the strip 13, When 2 the sliding'jwe'dg'e'isfin operative position.

Two spaced palr'sofguide" fingers 26 are car-' ried on the arms 25, rising fromv the inner edgesthereof, attheopposite ends of the 'arm'sj2 5. Q'The guide fingers are shown as extending from the outer edges of the arms '25 requirements of I a devicepbllitmany changes could beinade, in; the ,(abm c and beingbrought bac k'over' the upper face of theoarms'25 to. the inner edgesthereof and then directed upward-13 {Two pairsof outwardly directed "locking fingers 27 are also provided 011 the outeredg'e's of the arms 25for engagement 1 between "and co operation with thete'eth 23 onthe"flanges.22 ofthe legs 21 0f --theistripf131;to.regulateqthe position of the latter-and lock the same in "adjusted position,
